The IT insert fireplace offers your home tremendous heat without losing any room space. The height of the ITH model brings even more radiant warmth to your home. Both the IT and ITH inserts are available with either a matt black or nickel-plated frame. In addition to the comforting radiant heat they generate, these inserts allow the connection of vent tubes which recover the warmth around the heating body and channel it into the home instead of up the chimney.
